All the above structures are to be found and recognized during your laboratory class. Nevertheless,
knowledge about other structures mentioned in your textbooks and atlases is obligatory as well. We can ask
about them in the intermediate test and the final examination test. Some textbook figures can appear in the
MCQ questions.
